Factors affecting the price of rotary vane vacuum pumps

Speaking of vacuum pumps, I believe everyone has seen it in many fields. So what factors affect the price of vacuum pumps? Next, let's take a look at the price of vacuum pumps.

The price of rotary vane vacuum pump, factor 1, the regionality of rotary vane vacuum pump. Most domestic products are now facing the dilemma of having accessories but no technology, or having technology but no accessories. Because of the regionality of raw materials, the prices of rotary vane vacuum pumps vary.

The price of rotary vane vacuum pump, factor 2, the material of the rotary vane vacuum pump body is divided into ductile iron and gray cast iron: Ductile iron is obtained by spheroidizing and inoculating spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially improves the plasticity and toughness, thus obtaining a higher strength than carbon steel. Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its performance that it has been successfully used to cast some parts with complex forces and high requirements for strength, toughness and wear resistance.

Ductile iron has rapidly developed into a widely used cast iron material second only to gray cast iron. The so-called "iron instead of steel" mainly refers to ductile iron. Gray cast iron (gray iron) is cast iron obtained by fully carrying out the stage of graphitization process. All or all of the carbon exists in the form of flake graphite, and the fracture is grayish, hence the name. It includes general gray cast iron (abbreviated as gray cast iron), nodular cast iron, earth gray cast iron, etc. Gray cast iron, the appearance of its fracture is light gray, so it is called gray cast iron (gray iron). This is cheap and widely used. Gray cast iron accounts for more than 80% of the total output of cast iron.

The price of rotary vane vacuum pump, factor 3, the technical content of rotary vane vacuum pump is well known, the maturity of technology, high-standard processing and production equipment, the stability of performance, reliability and life of the products produced are all affected.

The price of rotary vane vacuum pump, factor 4, the quality of rotary vane vacuum pump accessories: the rotary vane vacuum pump is mainly composed of filter screen, marbles, exhaust hood, rear end plate, water cover plate, pulley, front axle, exhaust hood gasket, low rotor, exhaust valve plate, front end plate, oil sealing chamber, oil baffle, window, air inlet nozzle, high rotor, spring, pump housing, key, air injection valve, sealing ring, high rotor, locating pin, middle partition, bottom rotor, oil drain plug and other accessories. The quality of these accessories directly affects the price of rotary vane vacuum pump.
